A mini die grinder is like a dremel tool except a little slimmer and of course pneumatic. In fact the cut off wheel I used is a dremmel cut off wheel. What I did was carefully cut a horizontal slit in the connector so that I could peel it back and remove the end of the cable. You have to go real slow and easy so you dont cut the cable or the **** on the end of it. I used a good amount of anti sieze on both ends when I connected the new rear cable to the front.
The rear cables are easy to install. the driver's side just has a snap connector. The passenger side has a metal bracket that bolts to the axle. The new cable will have one already installed so just remove the bolt from the old one and re use it on the new one. There is also a clip on top of the pumpkin that the cable will run into. Running the cable is very easy. Remember to hook the new cables onto the ebrake hooks BEFORE connecting the front cable to the rear.
